Recortar com jcrop no php alterando a foto no banco de dados

rafael.munareto · Junho 29, 2019

Pessoal,

No código abaixo quero recortar a foto e subir o nome do arquivo na variável que busco no banco de dados, consegui fazer o efeito de recortar e de visualizar mas não está aparecendo a imagem recortada e nem salvando o nome do arquivo com a nova dimensão, podem me ajudar:

<?php
error_reporting(E_ALL ^ E_NOTICE);
require_once("mostra-alerta.php");
include("coneta_mysql.php");

*/

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$targ_w = $targ_h = 150;
$jpeg_quality = 90;

$src = "img/perfil/<?php echo $foto_perfil ; ?>";
$img_r = imagecreatefromjpeg($src);
$dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
$targ_w,$targ_h,$_POST['w'],$_POST['h']);

header('Content-type: image/jpeg');
imagejpeg($dst_r,null,$jpeg_quality);

exit;
}
?>

// Create variables (in this scope) to hold the API and image size
var jcrop_api, boundx, boundy;

$('#cropbox').Jcrop({
onChange: updatePreview,
onSelect: updatePreview,
aspectRatio: 1

},function(){
// Use the API to get the real image size
var bounds = this.getBounds();
boundx = bounds[0];
boundy = bounds[1];
// Store the API in the jcrop_api variable
jcrop_api = this;
});

function updatePreview(c)
{
if (parseInt(c.w) > 0)
{
var rx = 100 / c.w;
var ry = 100 / c.h;

$('#preview').css({
width: Math.round(rx * boundx) + 'px',
height: Math.round(ry * boundy) + 'px',
marginLeft: '-' + Math.round(rx * c.x) + 'px',
marginTop: '-' + Math.round(ry * c.y) + 'px'
});
}
};

$(function(){

$('#cropbox').Jcrop({
aspectRatio: 1,
onSelect: updateCoords
});

});

function updateCoords(c)
{
$('#x').val(c.x);
$('#y').val(c.y);
$('#w').val(c.w);
$('#h').val(c.h);
};

function checkCoords()
{
if (parseInt($('#w').val())) return true;
alert('Please select a crop region then press submit.');
return false;
};

});
